Overview In a dynamic AWS environment, elasticity is a core benefit, allowing infrastructure to scale automatically based on demand. However, this constant cycling of Amazon EC2 instances introduces a significant operational risk: abrupt termination of user sessions. When an instance is removed from a load balancer’s pool—whether due to a scaling event, a new deployment, […]

Overview In the dynamic AWS ecosystem, relying on legacy technology creates both security risks and financial waste. The AWS Classic Load Balancer (CLB) was a foundational service for distributing traffic, but it was designed for a simpler era of cloud computing. Operating at both the transport and application layers, it lacks the sophisticated features required […]

Overview In any AWS environment, Elastic Load Balancers (ELBs) act as the primary gateway for application traffic, directing requests to the appropriate backend resources like EC2 instances or containers. As this critical entry point, the ELB holds a wealth of information about every user and service interaction. However, by default, this information is not captured, […]

Overview A core principle of building resilient cloud architectures on Amazon Web Services (AWS) is leveraging its distributed infrastructure. AWS Regions are composed of multiple, isolated locations known as Availability Zones (AZs). The practice of distributing application components, particularly Amazon EC2 instances, across these zones is fundamental to achieving high availability and fault tolerance. When […]

Overview The security of data in transit is a non-negotiable aspect of a well-architected AWS environment. A common but critical oversight involves the security policies configured on AWS Classic Load Balancers (CLBs). These policies dictate the SSL/TLS protocols and ciphers used to encrypt traffic. When outdated policies are left in place, they permit the use […]
